【Abstract】 The zero drift resulting from the fluctuation of power and wavelength of SLD was analysed,and it was pointed out that the closed_loop approach can diminish the effect resulting from the fluctuation of optical power,and the comparison between SLD optical source and fiber optical source shows that fiber optical source with steady wavelength is a better choice for high_precision application.更多还原
